The present invention relates to novel pyrimidinyloxyalkanamide derivatives and agricultural or horticultural fungicides containing the same as active ingredients.
Japanese Patent Application, First Publication, No. Sho 63-132867 discloses that aryloxycarboxylic acid derivatives have fungicidal activities. In the previous application, compounds having 2-pyrimidinyl group without any substituents in the aryl group are disclosed; however, they do not exhibit adequate fungicidal activities. In addition, there is no disclosure of compounds having 4-pyrimidinyl group with substituents.
